Today we are watching some Mythbusters and looking specifically at how Archimedes attempted to make a death ray using soldier’s shields as reflective surfaces.  Do you think it is possible to use the reflected sun as a weapon?  Check out the worksheet from class and the episode below. Note: The video watched in class was regular speed and streamed from discovery education (which requires further passwords).  However, the video below also has the segments covered in this lesson (but you have to skip through a bit).

This week you will learn how light enters the human eye and is translated into vision.  Today we are studying the parts of the human eye.  Follow this link to quizlet to study the vocabulary and parts of the human eye. You can also watch the video below, which we watched in class.

We watched this first video to draw and label our own diagrams of the human eye

Then we watched this video to learn more about how the parts of the eye work and to complete our labelling

Then we watched this rather entertaining video that gets more in-depth about how the eye works.  It gets more in-depth than we are expecting students to know, but this fulsome information helps us understand how the eye really works, and shares really cool facts to support our learning.

Then, label the following diagram to show what you have learned. 19.02.05 human eye worksheet
